REGISTER HOOD.

Application filed March 29, 1926. Serial No. 98,211."

I This invention relates to heating and ventilating apparatus and more particularly to a register hood or cowl for diverting and controlling air currents to and from such register. I In the present invention there is contemplated a register hood comprising two tele sco ic sections arranged in overlapping sliding y adjustable relation, each embodying an'end wall and a portion of the top and rear wall of the hood, the base margins of the rear andend wall being flanged inwardly in .a common plane for projection beneath three margins of the engaged register plate. The rear wall marginal flange'of one section is reversely bent to slidingly enclose the corresponding flange of the other section While the front marginal edges of the top walls of the respective sections are rolled into tubular form, with one such tubular margins enclossections are interconnected by a spring, which tends to retract the telescopic hood, the sections of which are relatively adjustable to accommodate the hood to register. plates of different sizes, the engaged plate being gripped or confined between the end walls of the respective sections. In addition to the contractile spring, the end walls of the sections are inwardly deflected in forwardly convergent relation and are sufliciently flexible to be placed under inherent spring tensionbybeing flexed outwardly to substantially parallel relation, whereby such end walls will exert a contractile gripping influence upon the terminal marglns of the engaged register plate independent of the;

contractile spring connecting the sections.

The object of the invention is to simplify.

the structure as well as the means and mode of applying such hoods or cowlto hot air or ventilating registers or the like, whereby they will not only be cheapened in construction, but will be more eflicient in use, capa; ble of being easily and quickly attached and detached, adjustable to registers of different sizes and unlikely to et out of repair.

Cowls or hoods of the present type are usually employed in residences for diffusing warm air currents from a hot air heating system. They are also used in conjunction with ventilating systems for distribution of fresh air in residences, packing houses, warehouses and the like. As usually constructed, such hoods or cowls are subject to displacement and are easily disarranged or accidentally shifted out of registry with the hot or cold air register as the case may be, thereby ized. By the present construction the hood or cowl is adjustable to accommodate register plates of different sizes, thereby materially reducing the quantity of stock necessarily carried by the dealer or manufacturer,

and furthermore, the hoodor cowl is so engageable with the register plate that it will not .be easily displaced, and will tend to hold its engagement with the register plate. Furthermore, by contracting the hoods or cowls, such hoods or cowls may be arranged in less space for storage or shipment and may be conveniently and easily nested, one within another. a I 1 While'the invention is described primarily in its application to an adjustable register hood it is to be understood that it'is not limited to a register hood having telescopic adjustment, but certain features of the invention are applicable to register hoods made to fit registers of particular sizes and certain claims herein made cover such features apart from the feature of telescopic adjustment.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation or their equivalents as hereinafter described and set forth in the claims.

Referring to the accompanying drawings, wherein is shown the preferred, but obviously, not necessarily the only form of embodiment of the invention, Fig. 1 is a perspective view of the adjustable hood or cowl the relation of the slidingly engaged marginal flanges of the rear wall and the end wall flange with the register plate.

forming the subject matter hereof, applied section I Like parts are indicated by similar characters of reference throughout the several views.

In the drawings, 1 indicates the register late of a floor register. The hood or cowl ormi-ng the subject matter hereof, comprises end walls 22 which are inturned or flanged at their bottom margins as at 3."

Such flanges 3 project in substantially right angle relation with the end walls 22 and extend beneath the terminal margins of the register plate 1. Fixedly connected to the end walls 2- 2 are overlapping deflector sheets 44. The overlapping deflector sheets- 44 are of arcuate formation extendto slidingly enclose the inwardly flanged margin 6 of the other of the overlapping deflector sheets 4 4. At their forward margin the deflector. sheets 4 are rolled preferably downwardly and inwardly into tubular formation as shown at 7. The rolled margin of one sheet 4 is slidingly enclosed within the rolled margin 7 of the other sheet 4. These rolled tubular margins of the respective deflector.

sheets 4 are vpreferably of such relative size that one of the-tubular margins is under expansive tension orthe other under con- -tractive tension when interengaged, thus affording a yielding frictional engagement, which will tend to 'hold the parts in their adjusted relation. Each deflector portion 4 and its interconnected end wall 2 forms a unit or section which is telescopically adjustab1e in relation with the other unit or dornprising-the opposite end wall and other deflector sheet 4. TheQend walls and corresponding deflect-or sheets 4-4 forming the top and rear walls of the hood and cowl may be interconnected or joined in any suita le manner. The preferable method of uniting these portions is by means of a joint known to the tinning trade as a Pittsburg seam. Obviously, however,

- other forms of attachment or means of uniting the end walls and deflector sheet sections together may be employed. In making such assembly, theend walls 22 are preferably deflected inwardly -in forwardly convergent relation. as shown particularly in the plan view Fig. 3. The end walls 2 which are formed from sheet metal are sufficientlyflexible or yielding to allow these end walls to be sprung outwardly into substantially parallel relation. Such outward flexing of the end walls-22 into parallel relation subjects the walls to inherent spring tension,

by which the end walls tend to grip or clamp the register plate 1, interposed therebetween. By the sliding adjustment of the section of' the hood or cowl, such hood is accommodated to register plates 1 of various sizes. When adjusted to such size, however, the end walls 2 -2 by their deflection to parallel relation are under such spring tension as to exert a limited degree of compressive or contracti've pressure upon the end margins of the reg- .i'ster plate 1.'- The hood sections are held agalnst expansion under the reaction of such tension of the end wall 2 bythe frictional engagement of the tensioned tubular marginal rolls of the sheets 4-4 as before described and by the frictional engagement of the interlocked flanges 5'-6. To further re sist any such expansive tendency and to hold the hood in its adjusted relation with the register plate 1, the end walls 22 are preferably interconnected by a helical tension spring 8. In the drawings, such spring has been shown located at the lower rear corner of the end walls 22 and in close relation to the inturned' marginal flanges 56. However, this spring may be located at other points, and if so desired, an additional spring may be extended through the tubular rolled mar ins 7, ofthe deflector plates 4.
